Water drop on water-repellent soil surface

This photograph was shot on 8 February 2013 in a study area near Almadén de la Plata, in the Sierra Norte (Sevilla, Spain). We can see a water drop resting on a water-repellent soil surface.  This drop stayed for more than ten minutes without infiltrating.
